As for sammy's new chipset, I could care less. Quad cores on mobile platforms as it stands are useless. Optimization is what really matters, and that's not happening for quad cores (let alone dual cores) enough to make a difference. You'd think the S4 Pro would be a step up from dual cores, but the exynos 5250, a dual core, slaughters everything else on the market atm (ignore the Nexus 10's performance, that thing is just butchered). I'd stick with dual core's that take the 5250's route for the next year or two personally. Not saying the S4 Pro or other upcoming quads (OMAP5, tegra4, etc) aren't worth looking into, but it's not going to be the advantage many would expect. Not for a while that is.
